PACKAGING AND \VBAPPING MACHINE.

To all whom it may concem:

Be it known that I. Gnoaoi: 'lowxsuxn, residing at Mala Kasyonnie Peroulock, Sadovy" House, Cilivanofskie No. 13, Moscow. lathe Empire of Russia, engineer, have invent'ed; new and useful Improvements in Packaging and rapping Machines. of

which the following is a specification.

This invention relates to improvements in packaging machines, such as are used for packeting tea, coffee, dry soap, powdered and other dry'goods.

Hitherto difficulty has been experienced in closing the mouth or top of a packet after the material has been inserted into the packet so as to form a tight package in such a manner as to prevent material leaking therefrom.

Theobject of this invention is to overcomethe difiicul'ty hereinabove described when the lined or double bag is used for holding tea cotl'ee, etc., by providing means whereby a portion of the top end or ends of the lining or linings only of a packet or bag are first folded over the contents of said bag and afterward con'ipleting the fold of the bag by any well known means. The end of the bag or packet folded in this manner will first have the lining or linings alone at one side thereof folded on its con- 'tents within the upstanding portions of the lining and the outer bag before the latter are folded, so that when the bag or packet is opened to discharge the contents thereof, or for any other purpose, the fold of the lining first turned in will remain closed and prevent the contents of the bag escaping until said told is raised.

v This invention may be conveniently carried into practice by mechanism arranged as hereinafter, described, but which will require to be modified according to the type or class of packaging or packeting machine to which it is applied.

Figure-1 is a plan of a packaging machine provided with a rectangular track in which a numberof boxes containing the.

bags to be folded and closed are made to be intermittently traversed by means of plungers; Fig. 2 an end elevation of the same; Fig. 3 is a transverse section drawn to a larger scale on lines A, B, Figs. 1 and 5; Fig.4 is an enlarged transverse section on Specification of Letters Patent.

Figs. 3 to 33 inclusive are drawn to a larger scale than Figs. 1 and 2.

Like parts in all views are marked with similar letters of reference.

a is the f'amework of the machine, 1) its table, (1 the rectangular track open at its ends-in which the tour plungers (Z, c, f, g, are arranged to work. In the rectangular track are arranged a number of intermittently traveling boxes 71. which are propelled by the plungers (Z. a. 7', 1, according tothe direction in which they are required to travel. The paper bags to be folded are placed in these boxes with the upper 'portions of the bags projecting therefrom.

is the false bottom to the rectangular track upon which the boxes rest and travel.

j is the crease-r rod or bar which supports the device for creasing the paper folds of the bag.

All the above parts are of a similar description to those described in which the boxes are made to intern'iittently travel in a reciprocating track formed on the top of the table.

In order to separate a portion of the lining from the outer bag and to first fold the said separated portion prior to closing the lining of'the bag, mechanism constructed as follows may be used :-"-Toxtl'1ecreaser bar or rod 9' is fixed by any suitableineans a curved bracket 7c such as is shown at Figs. 3, 5, 19 and 20. This bracket is made to move up and down with the movement of the creaser bar or rod which is operated in any ordinary manner; and it embraces a vertical bracket Z which is fixed to the inner side of the rectangular track as shown at Fig. 3.

To the face of this bracket a cam piece m is fixed provided at its upper end with a circular portion a, a vertical portion 0 and a recess 72, at or near its lower end. To the upper surface of the rectangular track is fixed a bracket 1 the upper end 0* of which is turned at an angle inward toward the bracket Z. To the curved and moving bracket in are formed two arms L Fig. 20 to which the horizontal projecting arm of a plate t is jointed at s. The plate t is made to project above and below the arm t and its upper end a is bifurcated and turned in the same direction as the arm 25 toward the cam piecem so as to provide bearings for the runner c which works against the face of the cam piece. To the lower end of the plate 6 is fixed a thin metal plate or blade w which projects below the end of said plate. The end of the blade w is preferably made semicircular as shown at 15, but it may be of any other suitable shape. The blade to is employed for entering the mouth of the bag between the outer paper thereof and the lining y. The lining of the bag is made shorter than the outer portion of the bag.

On the moving bracket is provided a projection z in which is mounted and fixed a vertical bar 1, Figs. 9 and 10. The lower end of bar 1 is bifurcated to receive the slotted projection 2 formed on, or fixed to, the upper portion of a rammer or fiattener 3. The rammer or fiattener is shown'beveled or chamfered at 1 in order to more readily enter the mouth of the bag within the mold or receptacle h and the said flattener is in IJIVOtiIblG action by means of a pm 5 arranged to pass through the bifurcated end of bar 1 and the slot in the projection 2. On the upper surface of the fiattener is a projection 6 to which the end of a spring 7 is attached for keeping the plate normally in an inclined position as shown at Fig. 4.

8 is a. spiral spring which is employed for curved portion 22- on keeping the runner r against the face of the cam piece m. The ends of the spring 8 are v respectively attached to projection 9 formed on the plate t and to a vertical rod 10 fixed to the moving bracket 70. In Figs. 1 to 5, 19 and 20, the bracket is so formed that the means for separating the lining y from the outer paper (a will be at one point of rest in the circulatory movement of the boxes and the flattener 3 at the next stationary point in advance. Tn some cases it may be found more convenient to arrange for the lining to be folded inward and simultaneously flattened at the same point. When this is done the apparatus will require to be. slightly modified as shown at, Figs. 24 to 26.

To permit of this being done two narrow flatteners 3 are employed and arranged to work upon each side of the blade w, and instead of one bar being employed two vertical bars marked respectively 1 and 1 are employed for each fiattener 3. The vertical bars 1 and 1 are arranged to work through the extension pieces 11 and 12 which project respectively from the face of the holder 2. The vertical. bars 1 and 1 are also respectivcly jointed to a bar 13, the outer and free end of which is kept againsta stop 14. fixed to the bracket 1.b v means of a spring 15, the lower end of which is securedto a projection 16. fixed to the top of the rec tangular track 6. The bar 1 at a suitable distance from 1ts upper end may be'provi'ded with a curved projection 17 which forms a distance piece between it and the lever 1 The latter lever is also recessed or hooked at 18 to receive a thin metal spring plate 19, the inner end of which is fixed to a bracket 20 secured to the prolonged end of bracket 1. The two levers 1 and 1 are retained in con tact with each other by means of a spring 21. At a suitable distance from the, hooked or notched end of lever 1 is a pin or pro.- jection 22. To the arm t is jointed a hook 23 adapted to engage with the pm 22.

The action of the apparatusv is asfollows z-A bag having been placed in. the mold with its mouth upward as shown in the drawings and the contents having been measured or weighed and shaken therein, the creaser bar 1' is caused by cam 24:, lever 25, and link 26, to move downward, and as the creaserbar descends it carries with it the movable bracket 1: and the plate I- jointed thereto. and also the blade 10 which is fixed to said plate. In its normal position-the runner '2: will be on the top of the cam piece m and by the time it hasworked around the to the vertical portion 0 the plate t will have descended sufliciently far for the'blade 'w to have entered the mouth of the bag and have moved the outer paper :12 against the face of the angular por tion r of fixing g. This enables the blade as\it continues to descend to pass down between the'lining g and the inner surface i it the lining y over the contents of the bag 1n the direction of the dotted hues shown at Fig. at, thereby leaving the outer paper :1:

i in its vertical or upstanding position to be subsequently closed in the ordinary way. At the arrangement shown at Figs. 1 to 5 the plate and blade and parts connected there with would be returned to their normal position and the box moved under the creasing plate to be ra-nnned by the flattcner 3. but when the arrangement shown at Figs. 24- to 26 is employed simultaneously with the turning over of the lining 2 as described the two folders are brought into action by the spring 15 drawing lever 13 down and as soon as the inclined or chamfered end of the former comes in contact with the turned .in'porticn of the lining and contents of the bag by the said lever being held against the stop 1+, the continued downward movement of the bracket It. and plate 2 will cause the vflattcner 3 to he moved into a horizontal position by the rod l being unwed (lOYll ward and thus held tightly down for pressing the turned in portion of the lining on to the contents of the bag. In this arrangement until the bracket /v and plate 25 have traveled a sufficient distance to bring the hook 223 into contact with stop 22, the said tlatteners, bars 1 and 1 and lever 13 remain stationary afterward they travel downward with the said. bracket Zr and plate t andperform the functions described. By allowing the flattcners to remain stationary at the. b egii'ining of the operation, the blade N can enter the month of the bag and turn inward a portion of the lining 7 previous to r the fla'ttcners 3 being brought into operation. After the lining has been inturned, as hereinafter described. the bag is subjected to a set of devices for completing the operation of folding the bag. The first folder 50, Fig. Bl. operated by a lever 51 folds upon the inturned portion of said lining that side of the bag and its lining op posite said inturned portion of the lining, after which fingers 52 are moved and guided by pins 53 thereon and grooves 5410 fold thctwo remaining sides and their linings over the previously folded side, and finally the upstanding side of the bag alone is in e turned by a folder similar to folder 50.

It will readily be understood that although I have described the invention as being applied to the above named machine it can be readily modified to other makes or constructions of machine. the essential feature being to fold a portion of one or more of the lining or linings inwardly separate from the outer paper, and after the opposite side of the paper and its linings have been folded inward and then the fold completed in the usual way it thereby provides practically an air tight packet for preventing any leak age'of its contents, and one in which the inner lining end folds remain closed after the outerend folds have been opened.

It will readily be understood the herein described invention may be applied to wrapping machines as well as packaging machines.
